FINGER GUIDE DEVICE WITH RECESS

摘要

A finger guide device that positions a finger (or minutiae containing digit) of a human subject on a fingerprint sensor in a manner optimal for the data capture operation of authentication of identification of said subject, wherein a relevant portion of the finger is in alignment with a sensor or scanner. The finger guide device may also be used for enrollment of the initial fingerprint data into the system. The device may contain an outer surface ridge which feels somewhat uncomfortable due to application of a high pressure per square inch on small areas of the finger when the finger is incorrectly positioned to encourage correct placement of the finger. The finger guide device may have a curved inside surface to contour to a wide variety of fingertip shapes and sizes, wherein the sides and front have shorter radii of curvature than the rearward portion of the finger guide device

主权项

1. A finger guide device for mounting in alignment with a fingerprint sensor that has a sensor area smaller than a fingernail of an adult, comprising
a fingerprint sensor that has a sensor area smaller than a fingernail of an adult, a finger guide device having side surfaces that form a recess for receiving a person's finger and having an opening in which the fingerprint sensor is located,
whereby the finger guide device aligns the person's finger with the fingerprint sensor in essentially the same position in an axial direction when the finger is placed in the finger guide device to capture a relevant portion of the finger, said axial alignment occurring along a forward and backward portion of the finger guide device, andwhereby the finger guide device aligns the finger with the sensor in essentially the same position in a lateral direction when the finger is placed in the finger guide device to capture a relevant portion of a finger, said lateral alignment occurring between side edges of the finger guide device, the finger guide device enabling a relevant portion of the finger to rest in a stable position onto the fingerprint sensor each time authentication or confirmation is needed, the finger guide device reducing incidents of “false rejects” for purposes of identification or authentication of a person touching the finger guide device.
